Here's every Galaxy S phone since 2010

Samsung's 10th anniversary Galaxy S10 is coming, ushered in by rumors of multiple cameras, 3D face scanning and even the ability to wirelessly charge a pair of Galaxy Buds Bluetooth headphones. But Samsung's next venture wouldn't exist without all of the different Galaxy phones that came before it.

The Galaxy S10 and S10 Plus are expected to be Samsung's revamped phones, overhauling the hardware and software in important ways. We're expecting new additions to include the world's first ultrasonic in-screen fingerprint reader.

Rumored to be called the Galaxy S10 E (for "essential?") or GalaxyS10 Lite, the cheapest new Galaxy S10 model could have two cameras on the back for portrait shots. Not even the Galaxy S9 has that.

Back to the beginning, the first Galaxy S was announced at the Mobile World Congress trade show in Spain in 2010. Although Samsung had made smartphones before then, this was a true push for a higher-end device, and the global reputation that had eluded what is now one of the world's top smartphone brands.

The Galaxy S had a 4-inch Super AMOLED touchscreen, a 1GHz processor, a 5-megapixel rear camera (without a flash), 512MB RAM and Android 2.1 Eclair software. The battery had a "whopping" 1,500mAh capacity.

Each US carrier had a different variant it sold exclusively. T-Mobile's version had the same specs as the global edition, launching with 3G speeds.

Sprint's version strayed the most from the rest of the pack, with a slide-out QWERTY keyboard in addition to the touchscreen. Unlike the others, this one actually had a front-facing camera, rear camera flash and 4G speeds. The downside? Only 1GB of internal storage. Good thing it came with a 16GB external memory card.

AT&T's variant was physically edgier than the rest. There was no camera flash and no front-facing camera, but it did have 16GB of internal storage and a 2GB microSD card. AT&T followed up a year later with a slide-out keyboard version, the Captivate Glide.

Verizon also stepped up the base Galaxy S by including a camera flash and the ability to act as a mobile hotspot. However, it still only packed 2GB of internal storage (and 16GB more on an SD card) and lacked a front-facing shooter.

Samsung began churning out all sorts of Galaxy offshoots -- especially for each US carrier -- including this one with a secondary ticker display across the bottom. One of Samsung's attempts at a dual-screen phone, the Continuum never continued.

The global version of the Galaxy S II (or S2) became a much more modern-looking phone. Its screen size crept up to 4.3 inches. It also got a dual-core 1.2GHz processor, an 8-megapixel camera in the back, a 2-megapixel camera in the front and a 1,650mAh battery. 

In the US, the S II arrived for AT&T (left), Sprint (center) and T-Mobile (right). The varied physical designs were supposed to help carriers battle each other to sell what was essentially the same phone, with minor differences in screen size and processor speeds.

The Galaxy S3 was Samsung's first real Galaxy breakout. Hardware specs improved, of course, but it was the phone's pebble shape and pearly finish that also drew buyers in. It was also the first Galaxy to come to all US carriers without modifications, a sure signal that Samsung was gaining global clout.

After the Galaxy S3's success, Samsung announced a smaller version with stepped-down specs. The S3 Mini became one of an army of "mini" phones that followed the trend. It would be joined by the Galaxy S4 Mini and S5 Mini.

When the Galaxy S4 hit, Samsung had finally made it. The plasticky phone looked like a toy compared to rival HTC's gorgeous aluminum offerings, but it flooded buyers' senses with too many features to ignore -- including an IR blaster to act as a universal TV remote control.

Specs included a 5-inch Full HD Super AMOLED screen, a 13-megapixel rear camera, a 2-megapixel front-facing camera, a 2,600mAh battery and a ton of software extras.

This is what happens when you slap an optical zoom lens onto the back of a phone. It was... weird. But it also proved Samsung's willingness to keep trying new ideas. The clunky hybrid streamlined into a second Zoom, followed by two versions of a connected camera, which dropped the cellular radio.

The ruggedized GS4 spinoff expanded on the S4's core specs with a tougher exterior and physical navigation buttons, a water-resistant design -- unusual for 2013 -- and an underwater camera mode. It came in gray, bright orange and vivid blue. Samsung has released an Active every year since then, all the way up to this year's S8 Active.

Compared to the fresh feel of the Galaxy S4, the S5 was a nonessential upgrade that followed the exact same patterns. It was plastic (sporting a fingerprint-rebuffing matte finish this time), with a fingerprint reader and heart-rate monitor. The double-barreled charger port was a proprietary mess. Most exciting: It was water-resistant.

US carrier Sprint picked up this exclusive, which looked almost exactly like a pair of shoes I once had, and offered little other than that aesthetic to the S5. Here it sits on top of the S5 and the S5 Active at the bottom of the phone heap.

Wow, finally. That's what we said when Samsung's beautiful, first fully metal phone emerged. And the S6 Edge, which had two curved sides? Double wow. It took an already excellent powerhouse and made it feel like an impossibly slim, luxe piece of hardware. High-end features like an octa-core processor and 16-megapixel camera didn't hurt, either. 

This was Samsung telling the world it was ready for all-curve phones. A larger version of the Galaxy S6 Edge, the Edge Plus (or Edge+) was basically the Galaxy Note 5, minus the digital S Pen stylus. It had a large, curved 5.7-inch Super AMOLED screen, and cost in between the S6 Edge and curved-screen Note 5.

This special edition channeled Bruce Wayne's crime-fighting alter ego to promote the Batman video game Injustice: Gods Among Us. The all-black phone came with deep gold accents and a few themed software highlights, including a ringtone and Batman skins.

Well, almost ready for all-curve phones. The S7 Edge used its much larger, curved screen to justify a higher price than the S7 as Samsung perfected the production process on its wraparound displays and glass. S7: 5.1-inch screen; S7 Edge: 5.7-inch.

Both phones wowed us with their 2K screen resolution, whistle-quick chipset and photo quality.

Samsung made only 2,000 of these devices for fans watching the Olympic Games in Brazil. The sponsor also handed them out to the Games' 12,500 participating athletes.

Talk about an overhaul. For the first time, both Galaxy models came with curved sides by default, a larger screen with whisper-thin bezels, and a fingerprint reader that moves from the now-nonexistent home button beneath the screen to an awkward spot on the back, beside the camera. A new button pops up on the side for Bixby, Samsung's brand-new voice assistant.

The Galaxy S9 is an excellent phone, but isn't much of an upgrade from the S8. Also, there's no portrait mode, and its battery life was a disappointment. The S9 Plus however has dual cameras that coordinate to take great portrait photos. Plus, it has a large vibrant screen, and its battery lasted 2 and a half hours longer than the S8. 

If you're not planning to wait for the S10, the S9 Plus is the S9 to get. Hopefully Samsung will completely overhaul the design, as the current one is getting a bit stale. 

Are the Galaxy X and the rumored Galaxy S10 the same phone?! And if so, does that mean that the next major Galaxy phone will be foldable? We'll know more in the next few months. Stay tuned.
